Re: [linrad] Linrad installation and first impressions

[Stan <stan@xxxxxxxxxxxxxxx]

Hello Chris,

Congratulations on the progress.

What version of ALSA are you using ?   Latest is 1.0.4
What version Linrad ?

I am using Suse 9.0 pro with the normal distribution of ALSA like 
version 0.9.6 and I was having problems.

I changed to the OSS drivers and everything came up fine and I am 
playing with Linrad-01.18 now.
OSS deleted all of the ALSA drivers and loaded all of the oss drivers I 
needed, automatically.

Can anyone point me to where I can download  Linrad-01.18a   ?
